TRACTION-WHEEL CLEAT.

Application filed September 25, 1926. Serial No. 137.756.

It is customary for the manufacturers of be secured, one to each 'of the first menfarm tractors to provide traction wheelsfor tioned cleats, and comprises a plate 10 sethe tractors which have radially extending cured by a plurality of bolts 11 to the ra- 4 cleats thereon. These cleats, however, candially extending portion 10 of the main not always be practicably used for the reacleat.- A plurality of notches 12 are proson that the sharp edges thereof will damvided in the outer ends of the plates so age the surface with which they come in as to provide a plurality of ground-engagcontact unless such surface be a. material ing portions which will penetrate with such as earth. which is not affected by the greater easethan a single unitary surface of 10 cleats digging in. Furthermore, the much greater width. Thus, ground engag cleats as usually provided do not secure a ing prongs 13 are provided. traction suflicient to prevent the wheels from Each of the ground engaging prongs 13 slipping to a certain extent, with the result is bent over its extreme outer end to form that the tractor is often-times stalled under the flange let substantially at right angles to 15 conditions which longer cleats would ob-- the body of the cleat. \Vhen the traction viate. wheel is rotated the flanges 14: will form a It is the primary object of my invention, relatively flat surface which will prevent therefore, to provide an extension cleat for damage being done to the surface with traction rims which will give the necessary which theycontact, if such surface be a relatraction effect to prevent the wheels from tively hard one such as wood, concrete and slipping in soft material and which will also the like. The surface, however, is not of present a flattened contact surface which suflicient extension to prevent the cleat from will not dig in to wood, concrete or other entering a soft surface such as soft earth like surfaces. when it is desired that they so penetrate in 1th the above and other ob ects in view, order to obtain tractive effect.
